How many seeds have patents? How far has Genetic Modification gone?

I found a great site and PDF on which vegetables have patents, and the level of diversity in patents. While the patent community argues that this is nothing, in my world one is too many, given there are no real solid studies on human effects and casualty (and I have asked Monsanto and all the others, by email and phone conversations). The whole idea of patenting plants and allowing them to roam free over our world is greed and insanity at its best. But then, I had no problem with food before Monsanto. The industry wasn’t broke; there was nothing to fix. If only they had used their ingenuity in other ways, Monsanto could have been our best friend.
